Hi. Can someone please help me. This is our first go around and the girls are turning yellow. Ive got two purp d's, chernobyl, outdoor elephant, lemon grenade, and ak47. All are less than a month old. Last week they were transplanted from coco to Fox Farm Happy Frog. The girls are in a 4x4x10 tent with a 1000w HPS. Temp is a constant 78, humidity right around 60%. Ive got an XHale co2 bag in the tent and a duct fan running concurrently with the light. Nutes are Cutting Edge Solutions 3 part. Ive fed the three times...and then thought I over did it so I flushed them two days ago. PH is a litttle high...aroung 6.8/7 from normal tap water. I treated them today with ph6 treated water and epsons salt, thinking it was a mg deficiency and STILL NO CHANGE. Someone please help me!!
